Start-time ground fault detection selection

You can choose whether to make ground fault detection valid or invalid at a start.
Ground fault detection is executed only right after the start signal is input to the
inverter.
Parameter Name
Start-time ground

selection
CAUTION
1. If a ground fault is detected with "1" set in Pr. 40, alarm output "
and the output is shut off.
2. If the motor capacity is less than 0.1kW, ground fault protection may not be
provided.
REMARK
When a ground fault is detected with "1" set in Pr. 40, an approximate 20ms delay
occurs at every start.

.4.1

Up-to-frequency sensitivity

The ON range of the up-to-
frequency signal (SU) output
when the output frequency
reaches the running frequency
can be adjusted between 0 and
±100% of the running frequency.
This parameter can be used to
ensure that the running
frequency has been reached to
provide the operation start signal
etc. for related equipment.
